JAMES La., MOLISTER, or HALEsBoRo, NEWAYORK.- i 4` FmEAnMf 'u To all whom it mag/concern! Be it known thatI, J AMES R. McALIs'rER, a citizen of the United States, residing at Hailesboro, in the county of St. Lawrence and State of New .Y ork, have invented a new and useful Firearm, of which the following is a speci tication.

lgeneral class in which an auxiliary barrel is detachably mounted on the ordinary barrel; and the main object of the invention isto provide an auxiliary barrelof simple construction which carries its own breech block andV lock and does not in any manner interfere .with or necessitatechange in the construction of any portion of the firearm to which it is attached.

" .A further object of the invention is to provide an 'auxiliary barrel that may be quickly placed in position or removed and one which may be made and sold as a separate article of manufacture to be applied to existing firearms.

A still further object of the invention-is to provide a novel form of barrel having a swinging breech-block which' supports the ring-pin and all of its operating mechanism.

'- A still further object of the invention isto provide a simple form of securing device for holding the auxiliary barrel to an ordinary `single-barrel firearm. A

With these and other objects indview, as will more fully hereinafter appear,theV invention consists in certain novel features of construction and arrangement of parts, hereiny after fully described,- illustrated in the accoml ,'panying drawings, land particularly pointed out in the appended claims, it being undertood that various changes in thevform,pro

portions,r size, and minor vdetails of the structure may be made without departing from the spirit or sacricing any of the advantages of the invention.

In the accompanyingdrawings, Figure 1 is a side elevation of a portionof a firearm provided with an auxiliary barrel constructed in accordance with the invention.

Fig. 2 is a similar view of a portion of the same, taken from the side opposite that shown in Fig. 1. Fig. 3 is a plan view showing principally the breech end of the auxiliary barrel. Fig. 4 is a ldetail perspective view ofthe breechblock detached. Fig. 5 is a view similar to Fig. 4, illustrating the construction of the breech end of the barrel. Fig. 6 is a sectional planview 0f the breech-block. Fig. 7 is atransverse Specification of Letters Patent. l ippuoation'med Apr112a19o4. ssen No. 205.953.

This invention relates to firearms of thatv Patented Nov. 14, 1

sectional view on the line 7 7 of Fig. 1, trating means for locking the auxiliar; rel in place, v A

Similar numerals of reference are emp to indicate corresponding parts througho I several figures of the drawings.

The auxiliarybarrel is shown as'appl a wellknown type of single-barrel gu cludng a barrel 1 and stock 2. The' aux barrel'i' is secured in place by clips 3, i are bent at both ends to partly embrace of the barrels 1 and 4,' said clips being nected in pairs by screws 3', the atta means. being of such a simple nature tha person may readily place the auxiliary l; in position or remove the same. 'The br block 5 vis provided with a forwardly-ex ing arm 7, which {its in aslight recess 'fo in the under surface of theharrel and is nected to said barrel bya pivot stud or s 9, so that the breech-block may be re moved to open or closed position.

. breech end o f the barrel is provided w rearwardlyextending arm 14, forming -tically a continuation of the barrel, and minates in an inwardly-extending rib 15 rear wall of whichis slightly tapered, ani front wall of said rib forms a straight sl der ina plane at right angles to the enl the barrel. One side of the breech-blo slightly cut away, forming a recess .146, at the rear end of the recess is formed a n 17 of a shape corresponding to the rib 15 adapted to receive the same, while the d of the recess is about equal to the..thicls of the arm 14, so that when the breech-i is closed the sides of the barrel and block be in a continuous line. j

From that 'side o'f the breech-block opp the recessl extendsan arm 10, that te nates in an inwardly-projecting rib 11, the side of the barrel is provided with z cess 12 and a notch 13, adapted, respectii to receive the rib and arm, the depth of recess in this case being also equal 'to thickness of the arm. When the bre block is closed, the two ribs will enter two notches, and the opposite sides of block will thus be rmly held and rearv movement of the block prevented. It be observed that the breech end of the bz and the forward end of the breech-block arranged on slightly-curved lines, so

vthere will be no diiiiculty in ,swinging block'to open or closed position.

At one side of the breech-block is" piv ,f-lever 18, that may be turned on its ew 19-until itsforwardedgeengages he side of the barrel land retains 'th`e closed position; o V leech-block is provided with an mi'l'" for the passage of a firing-pin20, rojected 'by a spring 21, the sl'nng to force the pin in `the'direction'ffler of the cartridge.
